FREDERICK G. SARGENT, OF GRANITEVILLE, MASSACHUSETTS.

WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 433,581, dated August5, 1890.

Application filed July 26, 1887.

To all whom it may concern.-

Be it known that I, FREDERICK G. SARGENT, of Graniteville, in the countyof Middlesex and State of Massachusetts, have invented certain new anduseful Improvements in WVoolWVas'hing Machines, of which the followingis a specification.

My invention relates to wool-washing machines in which the wool isremoved from the bowl of the washing -machine and carried thence to thesqueezing or wringing rolls by a series of inclined teeth setin acarrier-bed; and it consists in an improved method of constructing andhanging the forks so as to give them as much throw as possible and keeptheir tines perpendicular, and in the construction and arrangement ofthe teeth aforesaid, whereby the wool is more certainly and evenly fedto the rolls, and in certain cleansing devices hereinafter described andclaimed, whereby the squeezingrolls and adjacent parts are freed fromthe filaments 'of wool sticking to them and the same returned to thebowl of the machine, and whereby the fiber on the carrier-bed is moreeffectively sprayed with the washing-fluid.

In the drawings, Figure l is a side elevation of the wool-washingmachine embodying my improvements. Fig. 2 is a side elevation of thesame with the side removed. Fig. 3 is a plan view of the same. Fig. 4 isa side view of the water-conduit O and sprinkling-box S. Fig. 5 is aplan view of a portion of the bowl of the machine, showing thesqueeze-rolls and the trough M below and behind them. Fig. 6 is anenlarged side view of a portion of the I reciprocating carrier E and theteeth by which the wool is removed from the bowl of the machine, showinga portion of the carrier-bed in section. Fig. 7 is an enlarged plan Viewof the carrier squeeze-roll end of the bowl with the carrier and itsmechanism removed, to

clearly show the carrier-bed and the shape andarrangem entofthespray-receiving trough beneath it. Fig. 8 is an elevation of the samewith the side of the bowl removed.

The machine is supported upon'a frame A, and consists of a long bowl ortrough B, which contains the cleansing-liquid, and into which the woolis fed at the point I). At the opposite end of the bowl B are placed thesqueez- $..i.1N..245,195. (No model.)

ing-rolls R B, through which the Wool passes on leaving the machine. Thewool on entering the trough at the point I) is fed over the perforatedfalse bottom Bof the bowl toward the wall of the chute b by the forks Fand F, which have at the same time a vertical and a horizontalreciprocating motion, such that the point of each time of the forksdescribes a complete ellipse at each stroke.

The forks F and F consist of a series of cross-bars 0 0, provided withdownwardlyprojecting tines o 0. The cross-bars 0 0 are attached rigidlyto a central longitudinal bar 0 The latter is provided on its upper sideand near its ends with the ears o 0 which are formed with transversepivot-holes. The arms 0 0 are pivoted to the bar 0 by pivots passingthrough these holes and the lower ends of said arm. Each arm is rigidlyat taohed at its central part to the sleeve 0 which is in turn attachedto the wrist-pin'of the crank 0 so that the latter can revolve freelytherein. Near the upper end of each arm 0 is attached rigidly the sleeve0 To the latter is pivoted the bifurcated end of the link 0 which hasits other end pivoted to an car 0 on the bar 0 of the frame, whichlatter is held in position by the pipe-sleeves in the usual manner, asshown. The cranks which revolve their wrist-pins in sleeves o o areattached to shafts which are geared together, as shown, by the train ofgears n 12 11 to. The effect of this construction is that the arms 0 0pivoted to each end of the bar 0 serve to give the rake, composed ofthis latter bar and the cross-bars o and. tines o a greater amount oflongitudinal movement in the bowl, while at the same time they carry thetines in the same vertical position at all parts of their movement, thuscausing them to enter and leave the wool in the bowl without draggingthrough it, as is the case when only one of the bars 0 is rigidlyattached to a fork, and it is provided with the crank-sleeve o andsleeve 0 and link 0 to drive it, the improvement in action being due tothe supporting of each fork F or F pivotally by two of these bars 0instead of by one rigidly.

The inclined carrier-bed T extends from the wall I) of the bowl B to thesqueezingrolls. It is provided .with teeth which incline. toward theupper end of the bed and serve to prevent the wool from traveling down.

The bars D D are pivoted to the frame of the machine at the points d d,and are connected at their upper ends by the tie 61'. They have rigidlyattached to them near their upper ends a carrier E, which is providedwith teeth.

The supplemental carrier G is pivoted to the carrier E at the points g gand is also provided with teeth. Its lower end is supported by therollers WV \V,which travel on the rails W \V'. The crank H is connectedto the tie d by the connecting-rod l. The link K is :pivoted at itslower end to the carrier G, and

its upper end is slotted and engages with ain on connectin -rod J. Thecrank H bein 23 3 b caused to revolve to the right, imparts areciprocating motion to the bars D D and the carriers E and G, and theconnecting-rod J, rising on its backward stroke and falling on itsforward stroke, by means of the link K, raises and lowers carrier Gcorrespondingly.

The teeth L L (see Fig. 6) are pivoted, re spectively, to the carriers Gand E, being inclined forward, and have stop-pins Z Z placed behind themto prevent their swinging backward. They are therefore free to swingforward only, and as the carriers G and E move backward glide easilyover the wool on the bed T; but as the carriers G and E move forwardthey take hold of the wool and force it toward the rolls R R. lVhen thewool arrives at the point I) of the bowl, it is seized by the teeth L ofthe supplemental carrier G and propelled up the bed T, and the teeth Lof the carrier E carry it to the rolls R R. Now, it has been found thatthe carrier E, having a reciprocating motion only and no rise and fall,its teeth L do not readily take hold of the wool. To avoid this, I makethe teeth with backwardly-bent points, as shown in Fig. 6, making theangle such that the points will be as nearly perpendicular as possibleat the beginning of the forward stroke of the carrier. This causes theteeth to take a more rank hold of the wool, while swinging downward totheir place, as the carrier begins to move forward,as they thus presenta greater angle to a horizontal plane at the beginning of said movement.The rotary pump P is driven from the pulley p and takes its liquid fromthe inclosed chamber V under the carrier-bed, discharging it through theconduit 0. The chamber V receives its fluid, to supply the place of thatwithdrawn by the pump, only from and through the perforations in itsupper portion,which are made' in the carriercarrier G.

(which is unperforated beyond the wall b',) and by the upwardly-inclinedpart of the bottom of the bowl and the vertical wall on of the trough M,as particularly shown in Figs. 7 and S. The trough M extends across bowlB, underneath and partly around the roll R, and when partially full ofliquid washes off from the roll all of the fiber, which then drops tothe bottom of the trough. This trough is formed on one side by thebottom of bowl B, which curves upward around the lower squeeze-roll R,and on its ends by the sides of the bowl B, and on its other side by thevertical wall m, which divides it underneath the carrier-bed fromchamber V. This wall m is carried back longitudinally at one endparallel with the side of the bowl for some distance, and thence to theside of the bowl, as shown in dotted lines in Fig. 7, and it is providedwith a tight bottom in this extended part joined to the side of the bowlB. This arrangement leaves room for the pipe N to be I carried throughthe side of the bowl and into the extension of the trough M to carry offthe washing-fluid, as hereinafter described.

The conduit 0 is supported by the standards A A of the frame, and,passing down to one side of the trough M, terminates in a fan-nozzle C,so directed horizontally at the mouth, as shown, as to sweep the troughfrom side to side of bowl B. In the conduit 0 is placed a three-way cockY, adapted to connect it by the conduit 0 with the sprinkling-box S,which is also supported by the standards A A of the frame. The liquidbeing turned into this box, it fills, and the liquid pours over thefront edge of the box, which is made lowest at its middle point, toinsure an even flow over the whole length of the edge, as the waterrushes towards the ends of the box when delivered into its bottom. Thewater from this box falls upon the wool at the upper end of the bed Tand additionally sprays it before it passes through the rolls.

By delivering the washing-fluid from the pipe G into the sprinkling-boxS and allowing it to overflow the edge of the box, as described, weprovide a sprinkling mechanism which is not liable to become clogged bythe fibers which are drawn with the washing-fluid from the chamber V,and at the same time sprinkles the woolwith an even amount of fluid atall times. The three-way cock Y may be so turned as to deliver the fluidfrom the pump P partly into the sprinkling-trough S and partly. throughthe fan-nozzle C or entirelyinto either, as desired. When the cock isturned so as to deliver the fluid through the fan-nozzle C, it sweepsthe contents of the trough M across to one end of the same and outthrough the conduit N back into the main part of the bowl B, thuscarrying with it all of the fiber which may have lodged in the troughMeither from the feed-rolls or from the action of the sprinkling-box Supon the wool on the perforated bed over it. When the fibers are thuscarried back by the conduit N into the main portion of the bowl, theyare again taken up by the fork F and carried forward with other wool inthe bowl to the squeeze-rolls.

The pump P, in taking water from the chamber underneath the perforatedbed T, creates a partial vacuum there, and in consequence draws thefluid through the wool upon the carrierbed and materially assists incleansing it. This action also creates a current from the main part ofthe bowl toward thecarrier-bed, which assists in transferring the fiberfrom the fork F to the supplemental carrier G.

What I claim as new and of my invention 1s 1. In combination, thecarrier bed T, the reciprocating tooth-bearing carrier E, and teeth L L,pivoted to the carrier E, substantially as set forth, and having theirlower ends bent backward, substantially as described.

2. In combination, squeeze roll R, the squeeze-roll R, the trough M,immediately beneath and partly surrounding it, a deliverypassage leadingout of said trough, the waterconduit 0 and nozzle 0, whereby the troughis adapted to be swept and cleansed by a current of liquid,substantially as and for the purpose set forth.

3. The combination of the carrier E, its bed above the surface of thefluid, the conduit 0, and the sprinkling-box S, placed over thecarrier-bed and adapted to sprinkle the fiber by the fiow of the sheetof fluid over its edge, substantially as described.

4. In combination, the perforated carrierbed T, the inclosed chamberbeneath it, the reciprocating carrier adapted to convey the fiber alongupon its upper surface, and the pump P adapted to draw the fluid fromthe said chamber and downward through the carrier-bed, substantially asdescribed.

5. The combination of the perforated carrier-bed T, the inclosed chamberV beneath it, the pump P, the conduit 0, provided with the nozzle 0',the squeeze-roll R, squeezeroll R, the trough M, and the pipe N, leadingtherefrom into the main portion of the bowl, substantially as described.

6. In combination, squeeze-roll R, the squeeze-roll R, the trough M,immediately beneath and partly surrounding it, the pipe N, leadingtherefrom into the bowl B, and the conduit 0 and nozzle Q, whereby thetrough is adapted to be swept and cleansed by a current of liquid,substantially as set forth.

7. The combination of the rake, composed of the longitudinal bar 0 andcross-bars and teeth 0', with two bars 0 pivoted thereto, two cranks 0 0connected to said bars, respectively, and carrying the same near theirmiddle parts, and two links 0 0 pivoted to said bars, respectively, attheir upper ends and to the frame, substantially as described.
